Definition (concept) of electronic whiteboard? thank you

Interactive electronic whiteboard is a new digital teaching demonstration equipment that replaces traditional blackboard and chalk in the world. It is a high-tech product developed by combining cutting-edge electronic technology, software technology and Internet technology. Its appearance is a revolutionary breakthrough to the old teaching mode of "trinity" of blackboard, chalk and eraser which has been followed for hundreds of years. Interactive whiteboard is an input device with human-computer interaction function based on PC. Connect with computer through USB interface, and cooperate with projector. The electronic pen replaces the mouse and the electronic whiteboard replaces the projection cloth, so you can operate the computer directly on the electronic whiteboard. It can easily realize the functions of writing, marking, geometric drawing, editing, printing, storage, remote interaction and so on. Through the use of projectors and computers online, as well as through the use of computer data processing functions and Internet information transmission functions. In addition, it can be used as the curtain of projector because of its good low reflection projection effect on the surface. Electronic whiteboard will become the main means of modern teaching, office meetings, distance education and information exchange in the future.

The interactive whiteboard is characterized by using reliable cutting-edge technology and unique technologies such as electromagnetic induction and digital positioning, connecting the whiteboard with computers and projectors, and building a huge interactive teaching demonstration environment with the support of powerful whiteboard software; The electronic whiteboard pen can replace the mouse to control the operation of any program of the computer host; The electronic whiteboard pen can be used to write, mark, modify, erase, save, play back and save files. The software has the functions of local amplification, local editing, searchlight, playback, calligraphy effect and so on, and has personalized templates, which can be continuously upgraded and expanded. High tracking accuracy, quick response and sensitive operation. Using advanced processing algorithm, the response speed and operating sensitivity of this electronic whiteboard far exceed those of pressure-sensitive electronic whiteboard and infrared ultrasonic electronic whiteboard. The surface material has low reflection, wear resistance, accurate focusing, excellent projection effect and no fatigue after long-term viewing. The board surface has a long service life and can bear tens of millions of irregular strokes of the pen tip; High precision positioning: the resolution is as high as 4096×4096. You can write beautiful Chinese characters, English, numbers or draw thin lines on the electronic whiteboard. Adopt independent intellectual property rights and proprietary sensor production technology.

Interactive whiteboard is suitable for finance, scientific research, engineering, project design, government, media, commerce, education, medical care, exhibition, security monitoring, military command and other fields.
